Provides a handy shortcut for allowing both sparse and unique indices on columns. MongoDB provides a method of only checking unique values where the field is not null (or 'sparse'). At present, using the
unique
andsparse
functions separately throws anMongoDuplicateKeyException
(see issue #556).You can get around this by using the
index
function, but my understanding is this should be avoided (please correct me if I'm wrong).
